MACHlNE'l-'OR MAKING PIPE.

SPECIFICATION forming part of Letters Patent No. 264,424, dated September 12,' 1882.

Application filed June 5, 1882. (No modelo To all whom it may concern.-

Be it known that I, THADDEUs H. WALSH, a citizen ofthe United States, residing at the city of New York, in the county and State of New York, have invented a n ew and useful Machine for Making' Pipe, of which the following is a specification.

This invention relates to certain improvements in machines for forming pipes from sheet Io material, such as paper, iron, and the like; and it has for its objects to provide certain means for carrying and guiding the sheets in the' process of formation, for forming the same into tubes or pipes, and for applying the cementing material necessary to hold the parts together, as more fully" hereinafter specitied. 'lhese objects I attain by the means illustrated in the accompanying dra\vings, in which- Figurev 1` represents a longitudinal vertical 2o section of my machine, and Fig. 2 a rear view of the same. The letter A indicates the frame of my machiue,`which is preferably constructed of angleiron.

The letters B and B indicate two rollers, suit- 3o motion is applied from a suitable source to theY machine.

The letter B2 indicates a guide-roller` which serves tognide and extend the belt D and keep` the belt taut. This rolleris provided with cogs at eacheud,which -cogs intergear with suitable cog-wheels, by which the rollers are driven.

'lhe letter l) indicates a'belt, which is pret'- erably made of canvas, in Width a little short ot the length of thel rollers, the ends being 4o fastened respectively to the rollers C and C.

The letter E indicates an iron tension-roller journaled in slots in a vibrating guidearm,F. The said arm is journaled in a brace aflxed to the frame A. At its outer end the said arm is provided with a weight or counter-balance, K.

The letter Gr indicates a weight or counterbalance attached to the vibrating arm or guide F by Ineans ofa chain, b, the lower connections of the chain passing over a small journaled 5o roller and attached to a pulley on the large wheel I.

A The letter H indicates a cylindrical hollowed former-roller,which is detachable from themachine, and which is tapered slightly from one end to the other.

.The letter I represents a large cogged wheel, as before mentioned,which is designed to raise the weight G to relieve the pressure upon the belt and the rollers and allow the weight G to turn the roller C, which takes-up the slack of 6 0 the belt until it is wound O' its fastened end on the roller G. The weight Gis attached to a grooved pulley on the roller G by a chain,

Aand the wheel I is provided with cogs, which intermesh with a cog-pinion having a crank,

F', by means of which it may be turned.

The letter L indicates a regulating and adjusting screw,which serves to adjust the bearing-rollers B and B.

The letters d d indicate iron adjustment- 7o guides, which serve to keep the cogs of the rollers B Bv constantly geared into the lower cogged wheel, to which said guides are Ajournaled, to conform to the different degrees ot' adjustment of the bearing-rollers.

The operation of myinvention is as follows: The former-roller H is first coated with a liquid preparation of ground chalk or soapstone in any convenient manner. The tension-roller E is then relieved of its attached weight, and 8o the wheel I is then checked by means ot' a pawl or otherwise. The tension-roller, being thus relieved of its weight, is raised by the balanceweight K on the end of the vibrating arm F. The upper weight, G', then causes the roller G 85 to revolve, which winds up all the slack ofthe A belt, the belt running olf the bottom roller, C', to its fastened end. When the tension-roller is raised a sufcient distance the former-roller H, of desired size, isplaced between it and the 9o bearing and power roller B, the bearing-rollers being lrst adjusted to receive it. When the former-rollerisinplace the wheelIis unchocked, the weight Gr lowered and its weight again thrown upon the tension-roller E, and the belt runs olf the roller U to its fastened end, and the roller C takes up whatever slack there may be in the belt. The various parts ofthe machine are then in position for the application of power, which is effected through roller B. Ioc A coating of asphalt is then spread upon the belt between 4the rollers B and B2, which is wound around thel roller H, forming :t lining for the pipe. A sheet of paper or other material is then luid on the surface ofthe belt and between the rollers B B2, and asphztltum is spread upon its surface. The sheet ofpaper is then Wound round the former-roller. Afterward :t sheet of iron is similarly treated and wound around the paper cylinder on the former-roller, and this process of treatment is carried on until the pipe is finished. The asphaltu m is heated to from 6000 to 800O,which causes the layers to adhere firmly. Vhile the pipe is thus being formed the Water-pipe I is caused to emit a spray of water upon the face ot' the belt to prevent the nsphztltum from stieliingto it. The ends ofthe pipe-may be cut smooth by n suitable knife forced against it as it revolves. When the pipe is completed the tensionroller is raised in the manner before described, the former-roller and pipe taken from the machine, the pipe drawn of` of the formerroller, when the machine is ready for further use.

2. In combination with the tension-roll, the M forming-roller, and the belt und carrying and supporting rollers, the bearing-roller B and its adjusting mechanism, substantially as and for the purposes specified.
